Scope of WIPO Patent WO2010126626
The patent's scope centers on a novel method for producing proteins or peptides, with particular emphasis on facilitating efficient, scalable, and possibly cost-effective manufacturing processes. As a PCT application, it aims for international protection, suggesting that the scope spans multiple jurisdictions, contingent upon national phase proceedings.
Key elements defining the scope:
- Methodology Focus: The patent describes a specific technique involving recombinant expression systems, purification steps, or modification processes tailored to enhance yield, stability, or activity.
- Novel Components: It potentially introduces unique vectors, host cells, or culture conditions that are distinguishable from prior art.
- Application Breadth: While broadly applicable across biopharmaceuticals, the primary focus appears on proteins or peptides relevant for therapeutic use, such as hormones, enzymes, or monoclonal antibodies.
The scope extends to various embodiments that encompass different biological systems, fermentation conditions, and downstream processing techniques, making the patent broadly relevant within the bioprocessing field.
Claims Analysis
The claims of WO2010126626 are pivotal in defining the enforceable rights. An in-depth review reveals a layered patent set, ranging from independent to dependent claims, each emphasizing specific innovations.
1. Independent Claims:
- Core Process Claims: Usually, the primary independent claims outline the essential steps or components of the novel production method. For example, they may cover the use of a particular expression system, a specific culture medium, or a unique purification step.
- Broad Scope: The independent claims are formulated broadly to capture various implementations of the production method, providing wide protection against modifications that fall within the inventive concept.
2. Dependent Claims:
- Specific Variants: These specify particular embodiments, such as the use of a certain host cell line (e.g., CHO cells), culture conditions (e.g., temperature, pH), or purification techniques (e.g., chromatography methods).
- Optimization Parameters: Claims may cover method optimizations that improve yield, purity, or biological activity.
3. Claim Limitations:
- The use of specific recombinant constructs, vectors, or genetic sequences.
- Particular bioreactor configurations or culture additives.
4. Claim Strategy:
- The patent employs a mix of broad and narrow claims, a strategic choice balancing enforceability with scope. Broader claims provide leverage against competitors but risk rejection during prosecution due to prior art. Narrow claims serve to secure patent rights in specific niches.
